COPPER WOLF OWNERSHIP CONSOLIDATION

IGO Limited (ASX: IGO) (“IGO”) is pleased to announce that it has entered into a binding agreement to acquire the remaining 49% joint venture interest in Copper Wolf, Arizona USA, (through its wholly owned subsidiary IGO US Project LLC) from Buxton Resources Arizona LLC (a wholly owned subsidiary of Buxton Resources Limited (Buxton) (ASX: BUX)) for a cash consideration of ~A$6.15 million, subject to Buxton shareholder approval.

On completion of the transaction IGO will hold 100% ownership of the central Copper Wolf area (~12.5km[2] ), including Bobcat, where drilling in 2023 returned 405m @ 0.35% Cu and 0.05% Mo,[1] and the supergene ‑ blanket at Rattler. The existing earn in and JV arrangements, which IGO had entered into in 2022 with Buxton, will be terminated.

Copper Wolf is located within one of the most prolific porphyry copper belts globally. Previous mapping and drilling have confirmed porphyry-style mineralisation and alteration throughout much of the project area. IGO is now focussed on a targeted drilling program, planned for 1H27, the results of which will inform next steps.

Ivan Vella, IGO Managing Director and Chief Executive Officer commented, “Consolidating full ownership of Copper Wolf is a logical and disciplined step aligned with IGO’s growth strategy to discover, develop and deliver battery minerals, including copper. The transaction simplifies the asset structure and provides IGO with direct exposure to an area with highly prospective geological potential in the globally significant Arizona copper belt.

Further work will be determined by the outcome of drilling in the project area and I look forward to providing updates as this progresses.”
